系統連系発電装置
Document Type and Number:
Japanese Patent JP4836447
Kind Code:
B2
Abstract:
An interconnected generator system comprises: a DC power generator means (1); an inverter circuit (3) operative to convert the DC power from the DC power generator means (1) into AC power; a current smoothing circuit (4) including a condenser (32) and operative to smooth the AC power converted at the inverter circuit (4); and a system open/close relay (6) operative to connect the current smoothing circuit (4) to an AC power system (7) in an open/close-switchable manner. A bypass circuit (51) is provided to bypass the system open/close relay (6) to connect the current smoothing circuit (4) to the AC power system (7). The bypass circuit (51) breaks the flow through the bypass circuit when a bypass open/close relay (57) is opened and connects the current smoothing circuit (4) to the AC power system (7) via a positive thermistor (56) when the bypass open/close relay (57) is closed.
